Separates the act of creating a TestNode object from starting the node.
The test_framework now keeps track of its list of TestNodes, and test
writers can call start_node() and stop_node() without having to update
the self.nodes list.
b8251f6 [tests] allow zmq test to be run in out-of-tree builds (John Newbery)
Tree-SHA512: 6946d23bc8a0b57e841a6811989182732d0534989e0e3b94421387f7971379b25a25d238cad22272e04076293275f6e980c8a713fce87ba48c1c4463d9243051
This commit uses the new skip test funcationality added in
232b6665bc to skip the zmq tests if the
python zmq module is not available or if bitcoind has been built without
zmq support.
This removes the zmq-specific logic from test_runner.py. In general it's
better if test_runner.py has no knowledge of special cases for
individual tests and is a general purpose test runner.
